IMPROVEMENT IN APPARATUS FOR PREPARING LAKES AND COLORS.

The' Schedule referred to in these Lettere Patent and making part of the same i I, JOHN LUCAS, of rhimaeipniaemmty of. ruimdelphia, State of Pennsylvania, have inventedcert-ain Processes and Apparatus for Preparing O olors, of' which'the following is a specification. 2 1

Nature and Objcctof the I accu-tion.

My invention consists of certain Lvautomatic ap paratus, too fully described hereafter to need preliminary explanation, for the mixing, chemically treating, washing, jconcentrating, and .compressing of colors.

Description of the Accompanying Draw-ing,

Figure 1 is-al side elevation, partly -i'n section, of my apparatus for' preparing colors;

Figure 2, a plan view ot' the upper portion of the same;. Figure 3, a sectional plan on the line 1. 2, lig-1; and

Figure 4,'a detached sectional view of part of the press'.V

General Descritioia The dotted-lines aaai, x, and w, are supposed to' represent the several floors ot' a building within which the apparatus is arranged, or they may represent a sexies of platt'orms forming'partof a suitable frame, constructed for the support of the appa- `Jatus.

Upon the upper floor n: is a raised platform, a, upon which are two, three, or more vessels, A, and above the latteris a mixing-box, B, provided'with-cocks l) vat the bottom, so that it may discharge its contents into sieves b1, V:n'ranged above the vessels A. A

- Within the box B is a vertical spindle, c, on'whi'ch is-a cross-piece with arms, forming a mixing or, "stir 'ring device, c", which maybe similar to that used in4 `brewers mash-tubs.

A reciprocating motion can be imparted. to the sieves b* above the vessels A'by a crank, b, on a vertical shaft, D, which turns in a step at )the bottom of a large vessel, E, on the door xl, and in a cross-piece which supports the vessel B.

vlThis shatt isdriven, iu 4the present instance, by a pulley, d, and is provided, within the vessel E, with a mixer, d', similar to that of the upper vessel B. The vessel E should be of sufficient capacity to re'- ceive the contents of all the vessels A, the said contents passing through cocks c? into receptacles el, and thence through pipes e.

A pipe, F, is provided with a suitable faucet, is arranged above and so that it may discharge water into the vessel E; and in one side of the latter is a rowiot cocks, jai-ranged at different heights above an. inclined trough, Ff

The-vessel. E has also, at a point beneath the lowest of .the cocks j, Aanother cock, 'g, fig. 2,

through which the concentrated contents ot' the said vessel may be drawn ott' into a spout, g',to bcthence conducted into a larger vessel, H, on the lower door a.

A ,This latter vessel,4 which is of s uiiicient capacity to receive the contents of two or more vessels E,

has within it .a vertical spindle and mixer, h, audit' has also a row of cocks, i, arranged at different heights above a spout, 'lhis vessel H Ais so arranged that its -contents may be drawn oli through a pipe, J, into a valvechest, I, bythe action of a pump, 1', and forced by the latter through another pipe or pipes,'J1, into pressesM, in which the color receives its fiualtreatment.

vA return pipe, J2, in vwhich is a safety-valve, l,-

press, in order that it may 4lie-connected to one ot'4 the branches ot' the pipe Ji, the latter having as many branches asthere are bags andspaces between the blocks, cach branch'b'eing provided'with a suita ble cock.

Thekseveral plates for-mingthepress arc drawn tightly together before the apparatusis put in opera# tion-by screw-rods q.

Operation; -The vessels A having been partially filled with the dil'ere'nt chemicalsnscd in the manufacture of the 4color which it is desired -to produce, the material which is to form thebody of the color is introduced into the box'B above the said vessels, and is then thoroughly mixed with water.

After this the cocks b are'then opened, either one ata time or simultaneously, and the mixture is per-' mitted to flow onto the reciprocating sieves b1, which serve as stra-iucrs, and prevent the admission into the vessels A of -any non-pulverized particles.

i Within the vessels A the material is. mixed with the'diierent chemicals with which it is to be treated,

and is thence, together with ythe chemicals, discharged into the receptacles ci, whence it flows through the pipes c into the vessels E beneath.

The receptacles cl are not in all cases necesf desired number 'of vessels E, and any appropn'ate number of vessels A with pipes and spouts, arranged substantially as described.

8. The' combination, with the vessel H and its agitator, of the pump herein described, or any equivaient pump, and the within-described press or presses and system of pipes, all arranged substantially as described 9L The safety-relire l'in the pipe leadingl from the force-pipe to the vessel H.

In testimony whereof Ilmve signed my name to this specification in the presence of two subscribing wit- DEBSBS.
